A pF ns
Short duration test pulse used to minimize self-heating effect. Part mounted on FR-4 board with recommended pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf. No purposefully added lead. Products manufactured with date code VD (Week 50, 2008) and newer are built with Green Molding Compound. Products manufactured with date code prior to VD are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants. 5. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dPD/dTJ < 1/RJA
